Hello
In my installation the disable_plaintext_auth does not appear to take
effect.
I can see that the value is correct using doveconf -a but it doesn't
change anything.
Whenever attempting to log in using IMAP I get this:
* BAD [ALERT] Plaintext authentication not allowed without SSL/TLS,
I just found the solution by coincidence.
It appears there is a configuration file named:
/etc/dovecot/conf.d/10-ssl.conf
In that file the following line was active ssl = required
That setting apparently overrides what disable_plaintext_auth has to say.
After commenting out the ssl=required
